And well this is basically my story as well. Except I didn't really started standing up for myself until I was in the 6th grade. People always made fun of me, and just for the exact same reason. I was unpopular, I was shy, I'm not rich. This generation has definitely changed. But I'm glad people like you stuck around.
To this day,I still don't have many friends, but they're allot more since when I was younger. The ones that did decided to be friends with me helped me change my life around. I finally got past the shyness stage, and like you,I want to help people who were like me, and get picked on. I wanted to thank you for writing this. Maybe some other people will realise the truth.
